Patented July 8, 1913.

To all whom it may concern Be it known that we, WILLIAM H. MORE- NUS, a. citizen of the United States, residing at Lake View, in the county of Sac and State of Iowa, and SAMUEL F. BEATTY and Curtis E. MOATS, both citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Double or Gang Road-Graders, of which the following is a specification.

This invention relates to earth-handling machines, and pertains more particularly to that class of machines known as. road graders.

The main object of the invention is 'to provide a machine of large capacity and capable of performing ..a large variety of operations, such as ditching, grading, scrap= ing, leveling, and the like.

In carryingout the invention weemploy as the chief novel feature thereof, a pairo scraper-blades, the scrapencarrying frames of which are hung from a corresponding pair of platforms, which latter are adjustable longitudinally of the main frame of the machine and are provided with means for independently raising, lowering and leveling the scrapencarrying frames, as well as for adjusting the angular ..posi-tionsof the scraper-bladesrelatively to their carrying frames and to each other, whereby said blades. may be so set as to perform the variousoperations referred to. v

=Our invention will bereadily understood companying drawings showing one practical mechanical embodiment thereof,'in which- Figure 1 is a side elevational view of the complete machine. Fig. 2 is a top plan, showing the scraper blades in the same rela tive position as in Fig. 1. Fig. 3 is another top plan showing a different adjustment of the scraper blades.

Referring to the drawings, 5 designates the longitudinal side bars, 6 the rear end crossbar, and 7 each of a pair ofatwin front crossbars secured to and connecting the forward ends of the side bars 5 =beneath the latter, an additional upper cross-bar 8 being also shown vertically above the inner lower cross-bar 7. The rear end of the main frame is supported in the usual manner upon a rearaxle 9 and rear wheels 10, and

the lower cross-bars 7 at the forward end of the main frame rest on a twin block bolster 11, in :turn supported on a center end of'the frame of a traction engine 18.

Centrally pivoted on the king-bolt =13 'between the center plate 12 and the inner end of the drawbar is a transverse draft-beam 19, the end portions of which are each formed with a plurality of apertures 20 and 20, respectively, which afford adjustable points of connection for the pivot-pins 21 and 21' of the supporting frames 22 and 22' of a pair of scraper blades 23 and 23. These latter, as usual in scrapers of this class, are rigidly secured by hangers 24, and 24 to turntables 25 and 25 pivotally suspended at 26 and 26' from the frames 22 and22 and provided with the usual segment racks 27 and 27' and pinions 28 and 28' operated through universal joint connections with steering posts 29 and 29. With the specific construction of the scrapercarrying frames and the specific .means for adjusting and locking the scraperblades thereon the present invention is not .concerned, as the parts and mechanism indicated for this purpose are old and .well known.

The pivoted'transverse draft-beam 19 has formed integral with its forwardside an internally notched arc-bar 30sliding through a keeper 31 on the upper side of the drawbar 14, whereby said transverse draft-beam 1.9 is adapted to be locked in the various angular positions by means ofa locking'bar 32 pivoted at 33 (Fig. 1) in the drawbar 1&1 and passing upwardly through a @lon 'itudinal slot 34 in the keeper 31. Said locliing bar 32 is normally drawn into .lockingengagement with one of the notches 30 of the arc-bar 30 by a spring 35 (Fig. 1) and the upper end of the bar 32 is connected by a short chain 36 with a lock-operating rod 37 extending rearwardly of the .main frame and having at its rear end a handle 37 whereby it may be operated, said operating rod being supported and ,guided in apertures in the front crossbar 8 and apost 38 on the main frame.

The main rectangular frame of the machine is provided with a pair of central longitudinal angle-bars 39 between the front and rear cross-bars, which angle-bars, in connection with the inwardly facing channel side bars 5, forms longitudinal ways supporting a pair of platforms 40 and 40. These platforms are each provided with operators seats 41 and 41, and with suitable uprights, such asthe posts 42, 43 and 42, 43 (Fig. 1) on which are mounted the raising, lowering and suspending means of the scraper-carrying frames 22 and 22. These means, which are in duplicate on each side of each platform, comprise essentially levers 44, 44 pivoted to the upper ends of posts 42, 42, suspension links 45, 45 connected respectively to the ends of rigid cross-bars 46, 46 of the scraperrcarrying frames, and connecting rods 47, 47 formed with racks 48, 48 engaged by gear pinion trains indicated as an entirety at 49 and 49 operated by hand wheels 50 and 50.

The relative positioning of the scraperblades in a variety of ways to effect the sev- .which the scraper-blade-carry'rng frames 22 eral kinds of operations referred to is effected partially, of course, by the angular adjustments of the scraper-blades on their in dividual carrying frames 22 and 22; and by their individual raisin and lowering mechanisms last described; %ut their correct relative position for many of the functions and operations of which the machine is capable is effected by adjustments of the supporting platforms 40 and 40' relatively to each other and to the main frame. These longitudinal adjustments of the platforms 40 and 40' are effected by means of a windlass 51 mounted in posts 52 on the rear end. ofthe main frame and provided with chains 53 and 53' connected to the platforms 40 and 40', respectively, and provided with a hand-wheel 54 for turning the same. The chains 53 and 53 are guided over pulleys 55, 55 anchored to the rear frame member 6 of the main frame. The chains 53 and 53 are wound in opposite directions on the Windlass 51, so that, as the latter is turned,

one chain is wound up while the other .is v v j art that the details of construction'and rela-x paid out, and vice versa. The forward ends of the platforms 40 and 41 are connected by chains 56 and 56' to the opposite ends of the pivoted transverse draft-beam 19, being conveniently connected to the pivot-bolts 21' by and 22' are pivoted. By reason of this construction, the turning of the Windlass 51 in either direction causes a simultaneous travel of the platforms 40 and 40- in opposite di-' rections longitudinally of the main frame,

when the locking-bar 32 has been retracted to permit such adjustment; the draft-beam in specific claims.

19, of course, turning angularly and the scraper-blades 23 and 23 being carried bodily in opposite directions during such adjustment. The platforms 40 and 40 being connected to the Windlass at one end and to the transverse draft-beam 19 at the other by the chain connections described, they are practically locked in any adjusted position i when the Windlass 51 is locked against turning by the usual pawl-and-ratchet means ordinarily employed for such purposes However, any suitable positive locking de vices bet-ween the platforms and their respective slideways may be employed, if desired.

A machine constructed substantially as described is capable of a large variety of adjustments of the two scraper-blades so as to effect. practically all of the earthhandling operations accomplished by the various types and kinds of machines of this 5 geuerallcharacter now in use. Figs. 2 and 3 show simply two relative positions which the scraper-blades may assume out of a large possible number. In Fig. 2 the blades are I shown as disposed in. oblique alinement wherein they effect a wide cutting or scrap ing action with delivery wholly to oneside. In Fig. 3 they areshown in ditching position, each blade being so disposed as to deliver beneath the'center of the machine. By reversing the relative positions or the blades from that shown in Fig. 3, the blades may be caused to separately deliver to the opposite sides of the machine. By raising one blade relativelv to the other when in the ob- 100 liquely alined position shown in Fig. 2, parallel grading at different levels may be performed with delivery wholly to one side of the machine. The provision for connect.- ing the forward ends of the scraper-frames 1.05 adjustably ata considerable variety of points on the transverse draft-beam 19 also contributes to the range of adjustability of the scraper-blades, as likewise to the variations in outside width of the spht e of action of the blades; and it being here noted that the described means whereby the scraperframes are suspended from the platforms are adapted to permit a considerable lateral swing of said scraper-frames in actibn.

It will be evident to those" skilled in the without depart-ingfrom the principle of the invention or sacrificing any of the advantages thereof. Hence, we do not limit the invention to the particular mechanism disclosed, except to the extent clearly'indicated We claim: 2 r 1.
